The TN Div. of Fire Prevention adopted the 2018 IRC with an effective date of 07/16/20. There is an undefined transition period for counties following the previous state code edition to update to the new edition. Counties which opt out and choose to adopt and enforce their own building code must use a code that is no older than 7 years from the most recently published edition. If their code is older than the 7 year cutoff, then the code adopted by the State (2018 IRC) applies. With the publication of the new 2021 IRC, this means TN counties adopting and enforcing their own code must use at least the 2015 IRC. Jurisdictions may opt out of the state building code by a 2/3 vote of the city or county’s legislative body. Jurisdictions may also choose to adopt and enforce a different code than the State code, but they cannot adopt and enforce a code older than 7 years compared to the most recently published version. If their code is older than the 7 year cutoff, then the State code (2018 IRC) applies. With the publication of the 2021 IRC, this means anything older than the 2015 IRC will trigger the State override. (11/20/20)
The color-coded analysis is based on the best available data and reflects the adoption status of the International Residential Code (IRC) and International Building Code (IBC). It does not reflect information regarding building code enforcement.
If you receive a gray color-coded finding for your search area, your community’s residential building code adoption status may not be available; however, you may contact your local government for the information. Please remember that mobile homes and manufactured housing are not constructed using the codes reflected in this analysis, so this website does not apply to those home types.
If you know that your community has adopted the International Residential Code, but you receive gray or other color findings in error, please use the “Share Data” button at the bottom of this page or email us at Info@Flash.org. We will evaluate and update the information.

Policy on Information and Services for Persons with Disabilities and Persons with Limited English Proficiency (LEP): FLASH is committed to providing individuals with disabilities or LEP an equal opportunity to participate in and benefit from FLASH programs, activities, and services. Individuals may request reasonable accommodations from FLASH that they believe will enable them to have equal opportunities to participate in our programs, activities, and services.
FLASH considers a reasonable accommodation as a change or modification to afford a qualified individual with a disability or LEP full enjoyment of FLASH programs or activities unless modifications of policies, practices, and procedures would fundamentally alter the nature of the program, service, or activity, or result in undue financial and administrative burdens to FLASH.
To request reasonable accommodations, contact Eric Vaughn, Executive Vice President, at eric@flash.org or via fax at 850-201-1067. While a reasonable accommodation request can be submitted anytime, FLASH requests at least three weeks’ advance notice for certain requests such as sign language interpretation, remote conference captioning services, or on-site translation services.
FLASH may consult with you in an interactive process to determine on a case-by-case basis what accommodations can be made. Questions will be limited to understanding the barrier to your ability to participate in the program or activity in which you are interested and the nature of an accommodation that will remove this barrier.
If FLASH determines that your requested accommodation would fundamentally alter the nature of the program or impose an undue financial or administrative burden, FLASH may deny your request. However, in the event that occurs, FLASH will work with you to try to identify an alternative accommodation that allows you to participate effectively in the program, activity, or service.
Policy and Notice of Nondiscrimination: FLASH complies with Federal civil rights laws and is committed to providing its programs and services without discrimination in accordance with the following:
It is against the law for FLASH to retaliate against anyone who takes action to oppose discrimination, files a grievance, or participates in the investigation of a grievance in accordance with the above authorities.
If you think that FLASH has failed to provide these services or discriminated in another way based on race, color, national origin (including language), disability, sex, age, or religion, you may contact Eric Vaughn, Executive Vice President, at eric@flash.org or via fax at 850-201-1067 to seek an informal resolution.
